Resolution

ulimit and sysctl programs allow to limit system-wide resource use.

To resolve the issue, you need to first check the ulimit settings. Performing the command below will give you the current value of your open files:

$ ulimit -a

Typically, we suggest this value to be set to 65536. To change the open files settings, do the following:

1) Open $/etc/sysctl.conf or $/etc/security/limits.conf

2) Add the following entries:

 soft nofile 65536
 hard nofile 65536

3) Log off, and then re-login.

4) Check to make sure the new value is reflected with the ulimit -n command.
